Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, and in particular to a novel temperature controller. Background Technology

[0002] Traditional electric kettle thermostats use a riveting structure to connect the L / N copper sleeve and the conductive spring. The conductive spring contacts then connect to the moving contact to turn on the power. This secondary riveting can easily cause excessive resistance, resulting in the riveting point burning out and preventing power from flowing, and it can also burn out the kettle. In addition, this riveting structure can only handle 5-7A current, and products with currents exceeding 7A have a lifespan of less than 3 months.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a new type of temperature controller that is simple in structure, has low resistance, long service life, good user experience, and strong practicality, so as to overcome the shortcomings of the existing technology.

[0005] A novel thermostat designed for this purpose includes a thermostat body, characterized in that: the thermostat body is provided with: A conductive component, wherein a first conductive contact is provided on the conductive component; A linkage conductive mechanism is provided, wherein a second conductive contact is provided on the linkage conductive mechanism; at least part of the linkage conductive mechanism is elastically movable on the thermostat body so that the first conductive contact and the second conductive contact can contact or separate.

[0006] A stationary contact piece extending toward the linkage conductive mechanism is integrally provided on the conductive component, and the first conductive contact is fixed on the stationary contact piece.

[0007] An upwardly extending tab is integrally provided on the conductive component, and one end of the extension tab is bent in the direction of the linkage conductive mechanism to form a stationary contact tab.

[0008] The linkage conductive mechanism includes a flexible movable contact piece, which is elastically and movably mounted on the thermostat body, and a second conductive contact is located at one end of the movable contact piece.

[0009] The thermostat body is also equipped with a support base, and a snap-fit ​​part is provided between the thermostat body and the support base. The support base is fixed to the thermostat body through the snap-fit ​​part, and the other end of the moving contact is pressed between the support base and the thermostat body.

[0010] The snap-fit ​​part includes a snap fastener on the support base and a snap hole on the thermostat body. The snap fastener and the snap hole are interlocked to fix the support base to the thermostat body.

[0011] The support base is provided with a positioning post, and the thermostat body is provided with a positioning hole. The positioning post is inserted into the positioning hole, and a slot is formed between the positioning post and the hole wall of the positioning hole. The extension piece is inserted into the slot.

[0012] The stationary contact piece is provided with a riveting hole, and the first conductive contact is provided with a riveting post. The riveting post is riveted onto the riveting hole so that the first conductive contact is fixed on the stationary contact piece.

[0013] The linkage conductive mechanism also includes a contact rod and a deformable detection piece. When the detection piece deforms with the temperature rise, it acts on the contact rod, causing the contact rod to drive the movable contact piece to move downward, thereby separating the first conductive contact from the second conductive contact. When the temperature drops, the detection piece deforms and resets, causing the movable contact piece to elastically reset upward, and the first conductive contact and the second conductive contact come into contact.

[0014] The support base is provided with a movable hole, and the contact rod is movably mounted on the movable hole.

[0015] This utility model's thermostat uses a new manufacturing process to design and rivet a contact point in the copper sleeve that directly contacts the moving contact piece. This reduces the resistance value and solves the problem of excessive resistance caused by secondary riveting, which can burn out the electric kettle. Without secondary riveting, the electric kettle's power can be reduced to within 13A, solving the problem of slow boiling in household electric kettles and extending the lifespan of appliances, greatly improving the user experience.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See Figures 1-11 This novel thermostat, applied to electric kettles, includes a thermostat body 1, on which are provided: Conductive component 2, with a first conductive contact 3 provided on it; The linkage conductive mechanism a is provided with a second conductive contact 4; at least part of the linkage conductive mechanism a is elastically movable on the thermostat body 1 so that the first conductive contact 3 and the second conductive contact 4 can contact or separate, thereby connecting or disconnecting the circuit.

[0029] The conductive component 2 is integrally provided with a stationary contact piece 5 extending in the direction of the linkage conductive mechanism a. The first conductive contact 3 is fixed at one end of the stationary contact piece 5. The conductive component 2 is a copper sleeve. The stationary contact piece 5 is equivalent to the conductive spring of a traditional thermostat. In a traditional thermostat, the copper sleeve and the conductive spring are set separately and are riveted together using a riveting structure. In this solution, the copper sleeve and the conductive spring are integrally formed, which can reduce the resistance value and solve the problem of excessive resistance value generated by secondary riveting that burns out the electric kettle.

[0030] The top of the conductive component 2 is integrally provided with an upwardly extending extension piece 6. One end of the extension piece 6 is bent in the direction of the linkage conductive mechanism a to form a stationary contact piece 5. The extension piece 6 and the stationary contact piece 5 are integrally provided.

[0031] The linkage conductive mechanism a includes a flexible movable contact 7, which is flexibly mounted on the thermostat body 1, and a second conductive contact 4 is located at one end of the movable contact 7.

[0032] The thermostat body 1 is also provided with a support base 8. A snap-fit ​​part is provided between the thermostat body 1 and the support base 8. The support base 8 is fixed to the thermostat body 1 through the snap-fit ​​part. The other end of the moving contact 7 is pressed between the support base 8 and the thermostat body 1. One end of the moving contact 7 is a free end and can swing up and down to close or open the thermostat.

[0033] The snap-fit ​​part includes a snap-fit ​​9 on the support base 8 and a snap-fit ​​hole 10 on the thermostat body 1. The snap-fit ​​9 and the snap-fit ​​hole 10 are snapped together to fix the support base 8 to the thermostat body 1. In the traditional method, the support base 8 and the thermostat body 1 are connected by screws. When the temperature of the moving contact 7 rises, the heat will be transferred to the support base 8. The support base 8 is made of plastic, which will melt when exposed to high temperatures, causing the screws to loosen and the fixation between the thermostat body 1 and the support base 8 to fail. In this solution, the snap-fit ​​9 is used for fixation. When the plastic melts at high temperatures, the snap-fit ​​9 will be more tightly fastened to the snap-fit ​​hole 10, and the fixation between the thermostat body 1 and the support base 8 will not fail.

[0034] The thermostat body 1 is provided with a positioning protrusion 21, the moving contact 7 is provided with a first through hole 22, and the support base 8 is provided with a second through hole 23. The positioning protrusion 21 passes through the first through hole 22 and is inserted into the second through hole 23 so that the moving contact 7 and the support base 8 are positioned on the thermostat body 1.

[0035] The support base 8 has a positioning post 11 at the bottom and a positioning hole 12 on the thermostat body 1. The positioning post 11 is inserted into the positioning hole 12, and a slot 13 is formed between the positioning post 11 and the hole wall of the positioning hole 12. The extension piece 6 is inserted into the slot 13, thereby positioning the conductive component 2.

[0036] One end of the stationary contact piece 5 is provided with a riveting hole 14, and the first conductive contact 3 is provided with a riveting post 15. The riveting post 15 is riveted to the riveting hole 14 so that the first conductive contact 3 is fixed on the stationary contact piece 5. The moving contact piece 7 and the second conductive contact 4 are also fixed by riveting.

[0037] The linkage conductive mechanism a also includes a contact rod 16 and a deformable detection piece 17. The detection piece 17 is a shape memory metal detection piece, which acts on the heating element of the electric kettle. When the temperature of the heating element reaches the disconnection set temperature of the thermostat, the detection piece 17 deforms and acts on the contact rod 16, causing the contact rod 16 to drive the movable contact 7 to move downward, thereby separating the first conductive contact 3 from the second conductive contact 4, thus putting the thermostat in the disconnected state. When the heating element cools down, the detection piece 17 deforms and resets, causing the movable contact 7 to elastically reset upward, and the first conductive contact 3 to contact the second conductive contact 4, thus closing the thermostat again.

[0038] The support base 8 is provided with a movable hole 18, and the contact rod 16 is movably mounted on the movable hole 18, which serves as a guide.

[0039] In this embodiment, two conductive elements 2 are provided, distributed inside and outside, namely an L-pole copper sleeve and an N-pole copper sleeve. Correspondingly, two stationary contact pieces 5 and two moving contact pieces 7 are also provided, with the two stationary contact pieces 5 being an L-pole conductive piece and an N-pole conductive piece, respectively.

[0040] The thermostat body 1 includes a base 19 and a bracket 20 connected to each other. A support 8 is disposed between the base 19 and the bracket 20. A conductive element 2 and a moving contact 7 are mounted on the base 19. A detection piece 17 is mounted on the bracket 20. A snap hole 10, a positioning hole 12 and a positioning protrusion 21 are disposed on the base 19.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
